The first duaa is known as the duaa of Abu Bakr radi Allahu anhu. In a hadeeth in Saheeh Bukhāri and Muslim, he narrated, “I asked Allāh‘s Apostle sal Allahu alayhi wa sallam to teach me an invocation so that I may invoke Allāh with it in my prayer. He told me to say,

“O Allāh, Indeed I have wronged myself excessively, and none can forgive sins except You, so forgive me out of Your forgiveness, and have mercy on me. Truly, You are the Oft- Forgiving, the Most Merciful.”
